Samsung may have lost a billion dollars to Apple in court, but the Korean company is claiming that Apple's iPhone 5 violates a host of Samsung patents. Samsung admitted that it investigated the product from release, suggesting that the company was preparing to launch a case against Apple.

"As soon as the iPhone 5 was available for purchase, Samsung began its investigation of the product," Samsung revealed. The company recently launched an advertisement directed at Apple.

Samsung claims that the iPhone 5 infringed on two "standard" patents and six "feature" patents, according to Bloomberg. Apple unveiled the iPhone 5 on Sept. 12, and it went on sale a week later on Sept. 19.

The case regarding the iPhone 5 is not scheduled for court until 2014, however. The eight patents are the same patents disputed in the first case between Apple and Samsung. In the previous case, in July, Judge Koh found that Samsung had infringed six of seven Apple patents.

Apple is also requesting a U.S. sales ban on Samsung's Galaxy Tab 10.1 and eight Samsung smartphones. On Oct. 1 District Judge Lucy Koh removed a U.S. sales ban for Samsung's Galaxy Tab 10.1, admitted in June. Apple said the ban should remain because Koh found Samsung's Galaxy Tab infringed "other" patents.

Apple claims that recently released Samsung products including Galaxy Note 10.1 will be added into infringement claims. Koh is scheduling Apple's appeal for U.S. sale bans of Samsung's Galaxy Tab in December. The District Judge will also consider Samsung's claim to remove the ban on the product, decided in August.

Samsung lost $1.05 billion to Apple during the original case for the patent dispute. The case focused around Samsung's design bearing resemblance to iPhones and iPads. After the verdict, Samsung described the result as a "bad day for the American consumer," and added the result was not final. Apple described the result as justified.

Apple spokesperson, Kristin Huget, declined to comment on Samsung's request.
